Comments [?]

Function Catalyzes the ATP- and NADPH-dependent reduction of carboxylic acids to the corresponding aldehydes.
Catalytic activity RHEA:50916: a carboxylate + ATP + H(+) + NADPH = AMP + an aldehyde + diphosphate + NADP(+)
Cofactor pantetheine 4'-phosphate
Note: Binds 1 phosphopantetheine covalently.
Domain The N-terminal domain likely catalyzes substrate activation by formation of an initial acyl-AMP intermediate, the central region contains the phosphopantetheine attachment site, and the C-terminal domain catalyzes the reduction by NADPH of the intermediate thioester formed from the attack of the phosphopantetheine thiol at the carbonyl carbon of acyl-AMP.
Similarity Belongs to the ATP-dependent AMP-binding enzyme family. Carboxylic acid reductase subfamily.
